AGILE Observations of the Gravitational-wave Source GW170817: Constraining Gamma-Ray Emission from an NS–NS Coalescence
AGILE Observations of the Gravitational-wave Source GW170817: Constraining Gamma-Ray Emission from an NS–NS Coalescence
The LIGO-Virgo Collaboration (LVC) detected, on 2017 August 17, an exceptional gravitational-wave (GW) event temporally consistent within $\sim\,1.7 \, \rm s$ with the GRB 1708117A observed by Fermi-GBM and INTEGRAL. The event turns out to be compatible with a neutron star-neutron star (NS-NS) coalescence that subsequently produced a radio/optical/X-ray transient …
